Real airplanes with real numbers: wingspan, flying weight, motor, ESC, battery, prop, servos and where the CG ended up. Every record says who measured it and whether it flew. Copy one straight into the designer or the electronics checklist.
Grows with every build and every reviewed community submission.
A 30-inch foam-board trainer or slow flyer flies on a 1806–2212-class brushless motor, a 30A ESC, a 3S 850–1500mAh LiPo and 9g servos at roughly 7–10 oz flying weight. Bigger planes step up in motor and cells with weight. The table below lists the exact combinations from planes that actually flew, labelled Eric tested, Community measured or Calculated estimate.
Wingspan, weight on a scale, motor, ESC, battery, prop, where the CG ended up, what failed and what fixed it. Eric reviews every submission; approved ones appear here labelled Community measured with your builder name.
